Cormorant
Cormorant
In Isaiah 34:11 and Zeph. 2:14 the Hebrew is qaath, and signifies PELICAN. In Leviticus 11:17 and Deuteronomy 14:17 the Hebrew word is shalak, and is rightly translated Cormorant, a large bird that lives upon fish. It dashes down upon its prey, and can follow it in the water or dive after it if it descends. It is only mentioned in scripture as an unclean bird.
